in this study the performance and emissions characteristics of a heavy-duty, direct injection, compression ignition (ci) engine which is specialized in agriculture, have been investigated experimentally. for this aim, the influence of injection timing, load, engine speed on power, brake specific fuel consumption (bsfc), peak pressure (pp), nitrogen oxides (nox), carbon dioxide (co2), carbon mon...

The aim of the present study was to investigate the effects of repeated injections of oxytocin on blood pressure and heart rate in spontaneously hypertensive rats (SHR). For this purpose subcutaneous (s.c.) injections of oxytocin 1 mg/kg or saline were given for 5 days to male and female SHR. Blood pressure and heart rate were measured daily before, during and after the oxytocin treatment perio...

Methods: A crossover randomized study of IVRA with a forearm tourniquet was conducted on 14 male healthy volunteers. This study was performed, once using manual injection of local anesthetic and once using automatic pump injection, on two separate sessions. In both techniques, 0.3 ml/kg lidocaine 0.5% was injected over 90 seconds. The occlusion pressure, continuous venous pressure and the serum...

Pollutant emissions from diesel engines are significantly affected by fuel injection strategies that could reduce NOx and Soot emissions. For the first time and in this study, numerical simulations were performed to consider the influences of changing the injection duration in each pulse of the double injection strategies on in-cylinder parameters and pollutant emissions. Results confirmed that...

BACKGROUND It is necessary to establish an effective subcutaneous injection procedure for adult and elderly individuals because many drugs such as hormones and interferon are generally delivered by subcutaneous injection. We tested whether pain during subcutaneous injection can be decreased by prior application of localized manual pressure at the injection site. METHODS In this semirandomized...

OBJECTIVE To describe the natural history of intraocular pressure (IOP) within the first 30 minutes after intravitreal injection of triamcinolone acetonide (TA). DESIGN Prospective, interventional, consecutive case series. PARTICIPANTS Thirty-eight consecutive patients who met inclusion and exclusion criteria and underwent intravitreal injection of 0.1 ml (4 mg) of TA were studied. METHOD...

• Shale Gas-In-Place calculations using the excess adsorption formalism. A novel Injection-Soak-Production scheme is proposed for enhanced gas recovery. proxy reservoir model used to compare injection CO 2 and N . Partial pressure competitive drive production complementarily. Natural extraction from shale formations has experienced a rapid growth in recent years, but low recovery observed many ...

Introduction: The central mechanism related to the cardiovascular response to lipopolysaccharide (LPS)-induced hypotension is not entirely known, but it is suggested that numerous brain areas such as dorsal periaqueductal gray (dPAG) are involved in this process. In the current work, the cardiovascular effect of the dPAG during LPS-induced hypotension is investigated. Methods: The study animal...
